Skewer doll on back of truck for return (5)
I believe the answer is:
kebab
'skewer' is the definition.
(I've seen this before)
'doll on back of truck for return' is the wordplay.
'doll' becomes 'babe' (I've seen this in another clue).
'on' means one lot of letters go next to another.
'back of' suggests the final letters.
'for return' says the letters should be written backwards.
The last letter of 'truck' is 'k'.
'babe'+'k'='babek'
'babek' backwards is 'KEBAB'.
(Other definitions for kebab that I've seen before include "Meat and/or vegetables cooked on skewer" , "Cubes of meat on a skewer" , "Fast food" , "Shish dish" , "Post-pub snack?" .)
